[PGT-A] Only three of 92 eggs were viable for embryo transfer

Mrs. Tsai, 42 years old, had previously undergone four unsuccessful IVF treatments at different hospital due to infertility. Eventually, she sought help from Dr. Maw-Sheng Lee, the head of Lee Women's Hospital.

Dr. Maw-Sheng Lee conducted an initial examination for Mrs. Tsai, and her AMH level was 2.83, which was considered quite good. Subsequently, an IVF treatment was initiated. Dr. Lee advised pre-implantation genetic testing for aneuploidy (PGT-A) to determine the chromosome status of the embryos prior to implantation because of the mother's advanced age. By doing this, it would be possible to prevent the transfer of embryos that have chromosomal abnormalities, improving the likelihood of a healthy pregnancy.

Mrs. Tsai underwent a total of 8 egg retrievals, yielding 92 eggs. The developmental rate was 23% since only 22 of them became blastocysts. Only one embryo and two mosaic embryos were discovered to have normal chromosomes following PGT-A chromosome screening. They finally figured out why she had been having fertility problems for so long.

It so happened that Dr. Chun-I Lee temporarily filled in during Dr. Maw-Sheng Lee's medical leave. After going over the reports on the embryos, he recommended implanting the best embryo that was found: a chromosomally normal embryo with an AI grade of 6+10=16 and a BHBA grade of 6. They additionally performed an ERA (Endometrial Receptivity Analysis) test to guarantee the ideal implantation window. Thankfully, Mrs. Tsai conceived following the successful implantation, giving birth to a healthy baby girl in 2021 at 37 weeks of pregnancy who weighed 2660 grams.

"I chose Dr. Maw-Sheng Lee because of his reputation, and he advised me to undergo PGT-A screening for embryos. This revealed the unexpectedly high percentage of embryos with chromosomal abnormalities. The process of egg retrieval and injections was physically and emotionally challenging. After a particularly disappointing egg retrieval, I arrived at Lee Women's Hospital in tears, forgetting even to check the pricing and bring my health insurance card. The two-hour wait after the embryo transfer for the pregnancy test results was agonizing. When we received the news of a successful pregnancy, my husband and I shed tears of joy. I encourage everyone to persevere and rely on their determination; you can definitely achieve success!"
